Palaeontology, and showed the origin of extensive deposits, 

 the nature of which had before been in doubt. Yon Buch, 

 Barrande, Beyrich, Berendt, Dunker, Geinitz, Heer, Homes, 

 Klipstein, Von Miiaster, Eeuss, Boemer, Sandberger, Suess, 

 Von Hagenow, Von Hauer, Zeiten, and many others, all aided 

 in the advancement of this branch of science. Angelin, His- 

 inger, and Nilsson, in Scandinavia ; Abich, DeWaldkeim, Eich- 

 wald, Keyserling, Kutorga, ISTordmann, Pander, Rouillier, and 

 Volborth, in Bussia ; and Pusch in Poland, published important 

 results on fossil invertebrates. 



The impetus given by Cuvier to the study of vertebrate fossils 

 extended over Europe, and great efforts were made to continue 

 discoveries in the direction he had so admirably pointed out. 



Louis Agassis (180T-73), a pupil of Cuvier, and long an 

 honored member of this association, attained eminence in the 

 study of ancient as well as of recent life. His great work on 

 Fossil Fishes* deserves to rank next to Cuvier's "Ossemens 

 Fossiles." The latter contained mainly fossil mammals and 

 reptiles, while the fishes were left without a historian till 

 Agassiz began his investigations. His studies had admirably 

 fitted him for the task, and his industry brought together a 

 vast array of facts bearing on the subject. The value of this 

 grand work consists not only in its faithful descriptions and 

 plates, but also in the more profound results it contained. 

 Agassiz first showed that there is a correspondence between 

 the succession of fishes in the rocks, and their embryonal 

 development. This is now thought to be one of the strongest 

 points in favor of evolution, although its discoverer interpreted 

 the facts as bearing the other way. 



Pander's memoirs on the fossil fishes of Bussia form a 

 worthy supplement to Agassiz's classic work. Brandt's publi- 

 cations are likewise of great value ; and those of Lund, in 

 Sweden, have an especial interest to Americans, in consecpience 

 of his researches in the caves of Brazil.
